Abstract (en)

A concealed hinge has a first base (10), a second base (20), a pivotal-connecting assembly (30), and a resetting assembly (40). The pivotal-connecting assembly (30) pivotally connects the first base (10) and the second base (20) and has a connecting block (31) moving during pivoting. The resetting assembly (40) has a resetting casing (41), a connecting rod (45), an elastic unit (74), and two oil-sealing rings (48). The connecting rod (45) is mounted in the resetting casing (41) and is connected to the connecting block (31). The elastic unit (47) moves the connecting block (31) via the connecting rod (45) to pivot the first base (10) and the second base (20). The oil-sealing rings (48) are sleeved on the connecting rod (45) and are attached to the resetting casing (41).
